INBDE Orthodontics Exam Questions
and Answers25
Endochondral Growth - ANSWERS-1. Growth from INSIDE
2. INCREASE in LENGTH
3. Under more DIRECT GENETIC Control
Zones of Endochondral Growth - ANSWERS-1. Zone of Resting Cartilage
2. Zone of Proliferating Cartilage
3. Zone of Hypertrophic Cartilage
4. Zone of Calcified Cartilage
5. Zone of Ossification
What areas undergo Endochondral Growth? - ANSWERS-1. LONG BONES
2. Synchondroses of CRANIAL BASE
3. CONDYLAR CARTILAGE of MD
Intramembranous Growth - ANSWERS-1. Growth from OUTSIDE
2. INCREASE in Diameter
3. Under more INFLUENTIAL Control
What areas undergo Intramembranous Growth? - ANSWERS-1. Sutures
2. On the Surfaces of Cranial Vault of MX
,Suture Theory - Harry Sicher - ANSWERS-1. Direct Genetic Control determines how bone is
going to grow
2. Sutures act as Growth Centers that push stuff apart
3. Mostly DEBUNKED because Sutures are REACTIVE rather than Proactive
Cartilage Theory - James Scott - ANSWERS-1. Epi-Genetic Growth Control has Cartilage pushing
and pulling things apart
2. Cartilage acts as Growth Centers and Bone follows along
3. Has some merit to it
Functional Matrix Theory - Melvin Moss - ANSWERS-1. Environmental Growth Control
2. Oral Functions cause the Nasal and Oral Cavities to grow bigger, thus Soft Tissue Matrix are
Growth Centers
Cranial Vault Growth - ANSWERS-1. Growing BRAIN pushes Cranial Bones APART
2. INTRAMEMBRANOUS OSSIFICATION at Fontanelles and Sutures + Internal and External
Surfaces
Cranial Base - ANSWERS-1. Made up of Ethmoid, Sphenoid and Occipital Bones, which are
initially CARTILAGE
2. ENDOCHONDRAL OSSIFICATION at SYNCHONDROSES
3. Intersphenoid
4. Spheno-Ethmoid
5. Spheno-Occipital
When does Intersphenoid Synchondrosis close? - ANSWERS-3yrs
When does Spheno-Ethmoid Synchondrosis close? - ANSWERS-7yrs
, When does Spheno-Occipital Synchondrosis close? - ANSWERS-Later
Maxillary Growth - ANSWERS-1. INTRAMEMBRANOUS Growth at Sutures POSTERIOR and
SUPERIOR to MX
2. Anterior MX undergoes RESORPTION
3. Palate, Alveolar Ridges and Tuberosities undergo APPOSITION
4. MX grows DOWNWARD and FORWARD
Mandibular Growth (Embryonic) - ANSWERS-1. INTRAMEMBRANOUS Growth to form RAMUS
2. ENDOCHONDRIAL Growth to form CONDYLAR CARTILAGE
3. These two FUSE at 4 Months in Utero
Mandibular Growth (Adult) - ANSWERS-1. ENDOCHONDRIAL OSSIFICATION as Condylar
Cartilage proliferates and produces bone
2. INTRAMEMBRANOUS OSSIFICATION to remodel surfaces
3. Anterior Ramus undergoes RESORPTION
4. Posterior Ramus, Chin, Coronoid and Alveolar Ridges undergo APPOSITION
5. MD grows DOWNWARD and FORWARD
Closing Rotation of MD - ANSWERS-1. Condylar Growth > Molar Eruption
2. Short Face
3. Deep Bite
Opening Rotation of MD - ANSWERS-1. Condylar Growth < Molar Eruption
2. Long Face
3. Open Bite
